Improvement in plow



UNITED STATES PATENT Ormea MOSES JOHNSON, OF THREE RIVERS, MICHIGAN.

IMPROVEMENT lN'l PLOW.

Specification forming part of Letters Patent No. 85,45 l, dated December29, 1868.

To all whom if. may concern:

Be it known that I, MOsEs JOHNSON, of Three Rivers, in the county of St.Joseph and State ot' Michigan, have invented a new and valuableImprovement in Plows; and I do hereby declare that .the following is afull, clear, and exact description of the construction and operation' ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference markedthereon. e

. Figure l of the drawings is a representation of a side view of mydevice; Fig. 2 is all inverted plan view thereof; and Figs. 3, 4,.`and 5are details.

The nature of my invention consists in providing for plow and cultivatorpurposes a series ot' corrugated convex wheels and adjust'- in g them tobeams set diagonally to the line ot' draft.

The letters A of the drawings are representations of mywhee'ls. Theperipheries of tllese wheels are corrugated, and the points of theVcorrugations ure made sharp,to enable theln to penetrate the groundwith greater ease. y I prefer to attach them to the beam by means ofpills and stirrups, as shown on Figs. l and 2; but they may also beattached by a variety of other means. The ,form 4, for example, is soconstructed asl to adapt it to revolving around a stationary axle,instead of being attached to the axle, which revolves on bearings in thestirrnps. Letters B represent the stirrups', andletters O the axles orpins. The letters D, on Figs. 1 and 2, represent the beams of the plow.LettcrE is theidrivers seat, and letter Gr the hook to which the motivepower is attached. Ihe'letter K is a punctnred arm adapt-ed to receive apin, M, and thereby-to regulate and gage the width of the furrow to beplowed. The manner of this adjust-ment is fullyshown in Fig. 2.

' Willen my'device is to be used for cultivat ing corn, potatoes, andthe like, it is sometimes desirable to adjust the wheels on both beamsso that the 'convex sides thereof shall stand all one way, and by thatmeans the furrow will be turned one way only, eitherto the right orleft, as the-operator may desire.

To plow a deep furrow, I adjust the beams of two witnesses.

Fig. 3. .represents .my device as applicable more especiallyto`field-plowing. It'consists of a tongue and cross-bar ofthe formrepresented, the' former of which is marked vO and -the latter P. Theletters a a al a showthe points at which the wheels are attached. Thebeam o r cross-bar P isadjustedon an angle of about iifty degrees withthe tongue, in order to place the convex wheels on the proper line withthe draft.

I usually placetwelve wheels on this beam P, and I find one team of twogood horses abundantly suflicient for its use, even ill greensward.

The fact that these wheels perform their oice -by a revolving motion,instead of the straight shoveling process of the commoll plow, securesfor my plow-a great saving of.' motive power. v

For greensward or rootysoil it is desirable to place revolving cutterson the bcaln l), in front of the wheels.-

The form of wheel sho'wn on Fig. et is sub- A It has wings, (marked b bb 11,) which, when in use, aid in segregating and loosening the soil..Figa 5 shows a method by which I sometimes construet the-corrugatedwheel. 1t is composed of a hnb,'je, resembling the comlnoll wagon-hubfor wheels, yand also arms d, to which convex and corrugated flanges arefirmly attached. Inthis form it is light and strong, and any worn-out orbroken ange may be easily replaced .by a new one. f

What I claim as my invention, and desire to secure by Letters Patent,is-

A plow having wheels A,beamsD,stir1-ups B, axles C, and punctured arm K,constructed, arranged, and operating substantially as described. 1

In testimony that I claim the above I have hereunto subscribed my namein the presence MOSES JOHNSON.

Witnesses;

L. N. STRAW, Jr., JNO. B. HANDY.
